Some 13,000 light-years away, in the Camelopardalis, or giraffe, constellation lies a rather unique binary star. Two young, massive, blue stars are orbiting each other so quickly that they make a full revolution in a mere 28 hours. In fact, the two stars of the MY Camelopardalis system are orbiting one another so closely that the outer layers of the stars actually touch one another.

Soon (or quite a while ago, rather) these two will merge completely, becoming one of the hottest and most massive stars in our galaxy, giving credit to the theory that the largest stars in our universe are products of smaller stars falling into one another. The newly combined MY Cam star will not have a very long lifespan, however. With such mass, the star will quickly die in a supernova, becoming one of the brightest spectacles in our night sky.
